Application filed January 2, 1909. Serial No. M0366.

To all whom it may concern: I 5

Be it known that I, SU L FFE H. EITHER, citizen of the United States, residing at Berkeley, in the county of Alameda and State of California, have invented new and useful Improvements in Carbonating-hllachine Equalizers, of which the following is a specification.

My invention relates to certain iniprove- 1 ments in carbonating machine zequalizers automatically regulate wherein gaseous matter sure.

It is the object of my invention to provide an equalizer whereby-simple means of ad justment are obtained, and in which efficient operation is efleoted. 7 j.

n t e piocess whereby carbonated; liquids are bottled iiilarge quantities for consumption, theusual method is to force the carbonic acid gas into the liquid during the operation of bottling. Storage, tanks containing aquantity of the gas under -pressure constitute the source of supply, suitable pumps being used --in connection therewith tozobtain the desired force. As the pressure that required in bottling, it IS necessary to utilizefsuitab'le In conjunction with such means: I provlde an adjustable equalizer whereby the of carbonic acid gas ecoiiies automatic. The invention consists of the parts, and'the construction and combination of parts hereinafter more fully described and claimed, having reference to the accompanying drawings, in which the figure is a sectional elevation.

A is a frame-work or support of any suitable construction in which are mounted the casings 2--3. \Vlthin the casing 2 are ar-. ranged the parts-"of a reducing valve which i may be of any suitable design, but in the one shown, consists of the throttle disks 4i5, and the diaphragm 6, attached to 7. A coil spring 8 acts on the spindle and The outer extremity of the spindle 7 is fitted in a sleeve 15, secured upon the spindle 7, a portion of which is threaded as at 16. The inner end of" the spindle 7 connected to a diaphragm 6 within the casing 3. A coil spring 17, placed between the nut 18 and the casing 3, acts upon the spindles 7-7, the diaphragms 6-6, and opposed to the spring 8.

To the casing 3 is attached a nipple 19 adapted to be connected with any suitable water-supply having a certain pressure, such l for instance, as that of a city main.

A pressure gage 13is provided for the purpose of indicating the water-pressure.

In the operation of the device, it will be obvious that when water under pressure is admitted to the chamber of easing 3, the spindles 77, are acted upon by the diaphragm 6, thereby causing the throttle valve at 4-5 to open and admit the flow of into the chamber 10, thence through the pipe and needle-valve toany desired outlet. As the admitted to'the chamber 10 is under pressure, the dia phragm 6 and the spindle, with its connections, are operated upon in opposition to the t is apparent that when the gas pressure in the chamber becomes parts resume the normal position shown in the drawings. While the needle-valve 12 is open, the flow of gas through the reducing valve becomes continuous, and is regulated and equalized by the device before descril:e l. In the event that the water pressure is lower than the desired pressure of gas, the action of the diaphragms, and their connections can be regulated by the adjustment of the nut 18 on the threaded spindle 7 against the spring 17. Thus, for example, assuming the water pressure in the chamber 3, to be lbs, and the desired gas pressure to be lbs, it will be seen that by compressingthe spring 17, to the desired extent addi tional pressure can he brought to bear upon the spindle f the spindles 77 in'such a manner as to perl mit of the required tends to normally retain the throttle disks in I water pressure in the mains constantly varies,

An equalizing device for opposed fluid E pressures, said device including a gas-receivi ing chamber, supply and discharge pipes con- Q nected therewith, an interposed double-seat- 3 ing throttle Valve, and closing spring therefor, a spindle to which the valve isfixed, a diaphragm on said spindle, a casing in which 1 the diaphragm is contained, a second casing to which a liquid is admitted, and a diaphragm in saidsecond casing and fixed to the 1 said spindle.

2. In an apparatus of the character described, diaphragm-containing chambers, an intermediate shaft or stem to opposite portions of which the diaphragnis are fixed, a gas supply and pressure chamber connected with one diaphragm chamber, a liquid supply connected to produce an opposed pressure upon the second diaphragm, a gas controlling throttle and spring by which the throttle is normally closed, and discharge l passage and pressure gage connected with the 'gas diaphragm chamben. a

3. In an apparatus of the character described, diaphragm-containing chambers, an
